Answer:
When F1 plant is subjected to self pollination, in the F2 generation, 3 tall plants and 1 dwarf plants are formed. In the one homozygous tall plant (TT), 2 heterozygous tall plants(Tt), one homozygous dwarf plant(tt) are formed. Phenotypic ratio is 3:1, genotypic ratio is 1:2:1. So, the correct option is '1:2:1'.
